单轴气浮平台的角动量测试系统设计

为了测量气浮平台台面上转动部件的角动量,需要测量气浮平台工作过程中诸如转速、转角以及转动惯量等物理量。为此,设计了一台单轴气浮平台的测试系统,描述了系统的整体结构和相关物理量的测量方法,介绍了系统各模块的硬件和软件设计,重点提出了气浮平台台上和台下相关性数据的时间同步方案。系统测试设备简单,具有很高的数据测量精度和相关性数据的时间同步精度。

Angular Momentum Test System Based on Single-axis Air Bearing Test-bed

In order to measure the angular momentum of rotating components on the test-bed,we need to measure some physical quanti-ties such as rotating speed,rotating angle and rotational inertia.Therefore,this paper designs the test system of single-axis air bearing test-bed,describes the massive structure of the test system and the method of measuring,introduces the design of hardware and soft-ware of each module in the system,and focuses on the time synchronization method of the correlative data on the test-bed and under the test-bed.The system is made up of brief equipments,and it can achieve high precision of data measurement and high time synchroniza-tion precision of correlative data.
